IMPROVEMENT IN VAPOR'BURNERS.

The Schedule efened to in these Letters Patent and'making part of the name.

I, ROBERT W. PRK, of Philadelphia,A county of Philadelphia, State of Pennsyvania, have invented an Improved Gas or Vapor-Burner, of 'which the following is a spccification.

My invention consists of certain improvemenls,-

too' fully described hereafter to need prcliminary explanation, in that class of burners which is supplied with naphtba or light oil from an elevated reservoir, and in which the said oil is converted into gas or Yapor before ignit-ion.

Description of the Aceompan'ying Draw-mg.

Figure 1 is a side view, partly in section, of my improved burner;

Figure 2 is a Vertical section of the same;

Figure 3, a plan View Figure 4, an enlarged sectional view of 'part of the burner;

Figure 5, an enlarged sectional plan on the line 1 2, fig. 2; and

General Description.

be vaporized by the application of heat so as to form an ignitable gas.

. A screw-valve, O, is furnished at its lower end with a suitable handle, a, extends vertically upward through the stem A, and termiuates at its upper end in a needle-point, b, adapted to a similarly-shaped seat in a tubular stem, A', which is secured to or forms part of the stem A.

vTheinterior of the stem A' is oonsiderably enlarged in diameter above the valve-seat, so as to form a chamber, x, and the said stem has one' or more apertures, c, for the admission of` air into the" said chamber, to be mixed with the vapor of the oil before ignition.

At the upper end of the stem A there is a tip or dome, D, in which is a transverse slit, d, for the passage of the mixed air and vapor, and below the dome, at opposite points, there are two minute apertures, c, for a purpose described hereafter.

A tube or sleeve, H, is-fitted over the stem A', and is secured to the latter or to the stem A by brazing or' otherwise. i

In the sides of the' sleeves, at points opposite to the air-passages c, arc cut openings or slits c', and from the upper end of the sleeve project two in- ,clined wings, J'J, 'which are arranged transversely iu respect to the slit (Z of the dome, andv'directly opposite and close to 'the apertures e of the stem, A'. 'The opposite sides of the stem A' are flattened or grooved, so as to form two channels or passages, h and h, between the said stem and the sleeve H.

- These passages extend nearly to the top of the sleeve, and communicate with each other at-their up- 'per ends by means of a circular groove, hl, cut in the stem.

Instead of cutting or flattening the stem, the passages h, 11,1, and W, might be formed by stamping up the sleeve in the manuer shown iu fig. 6.

A channel, i, forms a communication between the interior of the branch B and th'epassage h, and a similar channel, forms a communication between the passage 71. and the interior of the stem Af, below or., ,opposite the valve.

As there is uninterrupted -communication from the clevated reservoir through the branch B and channel-ii,

to the passages h, h1,and ha, and channel 41', the latter,

while the'buruer is not in use, will be filled with the light oil or other fluid from the reservoir. This oil is partially vapori'zed before lighting the burner by heating tbe-latter, the valve being lowered from its seat, so as to.. permit the passage ot' the partially-vaporized oilinto the air or mixing-chamber'x of the stem A'.

As the vapor'is generated, it passes upward through the cbamber a: and becomes mixed with the air, which enters the saidfchamber through the aperturesc.

This mixed air and'vapor is ignited as it emerges from the burner proper or tip D, and forms a broad fiame, closcly resembling an ordinary gas-jet.

The mixed air and gas which passes through the apertures e at either side of the tube is also ignited, and forming two fine jets, which play upon the inclined wings J- J, throughout almost their entire length, and highly heat the said wings.

This heat is transmitted to the tube or sleeve H,

and also to the inner tubnlar stem A', so that the oil, .in passing through the passag'es h, h, h, formed between the said sleeve and stem, will be thorougbly vaf porized, and will pass'into the mixing-chamber x, and 'from lthe apertures e and slit (Z, with a considerable degree of pressure.. I

` By-causing jets of ignited gas to heat simple ,wings or plates, so. arranged that they may transmit their heat tov the oil or vapor-passages, instead of causing jets or a broad flame to play directly upon tubes in which the vapor-passages are arranged as in other burners 'of this class, quite as effective a burner is obtained, while its construction is very considerably simplified. o

The method of forming the oil or vaporizing passages between two tubes also simplifies and reduces the cost of the burn'er.

1. The wings or plates J J, heated by independent jets of i gnit-ed gas from the apertnres e, in combination -With oil or vzipor-passnges' situated below the-,said

4. The tube 01' sleeve H, formed in one pie-oe with the wings Ji, and m'mnged to be fitted over and seenx'ed to the body of the bni'nex', as speeified.

In testimony whereof Ihnve signefi my name to this specification in the presenoe of two subscribing witnesses.
